The thesis analyses the criteria for evaluating the efficiency of real estate investment projects based on scientific literature and international valuation standards applied in practice. Using multi- criteria evaluation methods and based on the data of an empirical study carried out among groups of experts in real estate industry, the significance of indicators affecting the value of real estate investment projects in the long term is determined and an economic sustainability index of real estate investment projects is developed. This paper presents an economic sustainability index for real estate investment projects, which complements the discounted cash flow approach by applying a discount rate adjusted by a correction factor to assess the risk of asset depreciation and/or the potential for asset appreciation in relation to its long-term investment value. The proposed model allows for a comparative analysis of different investment projects, covering economic, social and environmental aspects. The proposed model provides an integrated assessment of real estate investment projects, which alllows to make the most appropriate investment decisions, focusing on the long-term value of the real estate asset. The thesis consists of: 75 pages without appendices, 25 tables, 17 figures, 66 bibliographic sources. The appendices are attached separately
Middle-term field research on air and noise pollution in the city district of Baltic region
No full textAir quality monitoring, as well as physical pollution, in particular noise, is an important component for assessing the quality of life in cities and their regions. Detailed and accurate studies require an analysis of the results obtained with at least an average time interval, which was carried out in this study of the environmental situation in the area of the city of the Baltic region. The results obtained can identify the main areas of greater pollution, enabling new planning of communication systems in small towns, as well as avoiding negative effects on the body of residents, thereby improving overall health. The data was obtained using a mobile laboratory and high-precision equipment, based on international standards for parameter measurement techniques. According to the results of the research, trends were found to reduce particulate matter up to 10 microns, depending on the seasons, by more than 10%. The noise level in most of the area remains unchanged, or gradually increases due to large traffic flows. In contrast to the recreational area, the greatest increase in pollution in the residential area found PM10, NO2 and benzene, by 30%, 39% and 72% respectively. In the area adjacent to the road infrastructure, concentrations of benzene, ethylbenzene and toluene were 37–54% higher than in the recreational area. The average concentrations of other pollutants were lower

Machine-learning-based password-strength-estimation approach for passwords of Lithuanian context
No full textIn an information-security-assurance system, humans are usually the weakest link. It is partly related to insufficient cybersecurity knowledge and the ignorance of standard security recommendations. Consequently, the required password-strength requirements in information systems are the minimum of what can be done to ensure system security. Therefore, it is important to use up-to-date and context-sensitive password-strength-estimation systems. However, minor languages are ignored, and password strength is usually estimated using English-only dictionaries. To change the situation, a machine learning approach was proposed in this article to support a more realistic model to estimate the strength of Lithuanian user passwords. A newly compiled dataset of password strength was produced. It integrated both international- and Lithuanian-language-specific passwords, including 6 commonly used password features and 36 similarity metrics for each item (4 similarity metrics for 9 different dictionaries). The proposed solution predicts the password strength of five classes with 77% accuracy. Taking into account the complexity of the accuracy of the Lithuanian language, the achieved result is adequate, as the availability of intelligent Lithuanian-language-specific password-cracking tools is not widely available yet.iss. 13vol. 1

BiomacEMG: a Pareto-optimized system for assessing and recognizing hand movement to track rehabilitation progress
No full textOne of the most difficult components of stroke therapy is regaining hand mobility. This research describes a preliminary approach to robot-assisted hand motion therapy. Our objectives were twofold: First, we used machine learning approaches to determine and describe hand motion patterns in healthy people. Surface electrodes were used to collect electromyographic (EMG) data from the forearm’s flexion and extension muscles. The time and frequency characteristics were used as parameters in machine learning algorithms to recognize seven hand gestures and track rehabilitation progress. Eight EMG sensors were used to capture each contraction of the arm muscles during one of the seven actions. Feature selection was performed using the Pareto front. Our system was able to reconstruct the kinematics of hand/finger movement and simulate the behaviour of every motion pattern. Analysis has revealed that gesture categories substantially overlap in the feature space. The correlation of the computed joint trajectories based on EMG and the monitored hand movement was 0.96 on average. Moreover, statistical research conducted on various machine learning setups revealed a 92% accuracy in measuring the precision of finger motion patterns.iss. 9vol. 1

The work was based on existing sinusoidal beam research papers, normative documents and manufacturer's instructions. 2 and 5 ton lifting capacity sinusoidal beams were investigated. It has been found that a sinusoidal beam can be adapted to brdige cranes, but due to length limitations it is not suitable for every case
Applying sustainable leadership for organizational changes toward sustainability
No full textThe ability to lead and effectively manage change is one of the most critical factors in leadership. In today’s changes in the economy and social well-being, various leadership styles are being used, which are applied in the context of the processes of today’s globalization. Leadership has become a highly significant concept in the twenty-first-century context. The scientific literature presents and analyses various leadership styles but does not sufficiently provide practical tools to identify the possibilities of human potential and ensure sustainable management. To improve the microclimate and interpersonal trust of the institution, the most crucial role is played by leadership style, change management, creativity, and giving feedback. The article formulates tasks: to reveal the transformation of attitudes toward leadership by comparing the factors of different leadership styles that influence the team’s focus on achieving the sustainable goals set by the organization. The results of the paper show sustainability could be reached in the organization if the organization’s managers apply sustainable leadership practices.Taip / YesI
